    摘要: An apparatus for determining an initial flow rate (Q) of a liquid in a conduit (10), comprising:
    (a) a means (20, 22, 70, 90) for introducing a change of a known volume of liquid over a known time to the initial flow rate (Q);
    (b) a sensor (50, 50', 50", 72, 92) located downstream from the point for where a known liquid volume over a known time is introduced, the sensor (50, 50', 50", 72, 92) measuring a flow corresponding parameter; and
    (c) a controller (100) connected to the sensor (50, 50', 50", 72, 92), the controller (100) being configured to determine the initial flow rate (Q) in response to the relative change (Cd) in the flow corresponding parameter downstream from where the flow is changed and the introduced known liquid volume over a known time, corresponding to Q = Q i C d ,
    where Cd = ΔQd/Qd is the relative change in the measured flow corresponding parameter.

    摘要: A catheter for retrograde orientation in a blood flow is used to determine the blood flow rate by thermodilution measurements. The determination of the blood flow rate accommodates injectate induced thermal influences on a dilution thermal sensor, wherein the thermal influences can occur prior to introduction of the injectate into the blood flow.
